Scan-Speak Discovery 22W/4534G00 Woofer

The Scan-Speak Discovery 22W/4534G00 Woofer is a high-performance 8-inch driver engineered to deliver deep, controlled bass with exceptional clarity. As part of the renowned Discovery series, this woofer combines advanced materials with precise construction, making it an ideal choice for audiophiles and DIY speaker builders seeking to elevate their sound systems. Whether used in a dedicated subwoofer enclosure, a two-way bookshelf design, or as the low-frequency foundation of a multi-channel home theatre setup, this driver excels in reproducing impactful, low-distortion bass across a wide range of applications.

Technically, the woofer features a lightweight yet rigid glass fibre cone, which minimises cone breakup and ensures accurate transient response. The robust aluminium frame provides a non-resonant foundation, reducing unwanted vibrations and enhancing overall stability. With a sensitivity of 92.5 dB (1m/2.83V) and a total Q factor (Qts) of 0.34, it is well-suited for both sealed and vented enclosures, offering flexibility in design. The 3-ohm DC resistance (Re) and low voice coil inductance (Le: 0.55 mH) contribute to efficient power handling and controlled impedance behaviour. Additionally, the woofer’s mechanical (Qms: 3.7) and electrical (Qes: 0.37) damping characteristics ensure tight, articulate bass reproduction. With a mounting cut-out diameter of 184.7 mm and a depth of 89.7 mm, this driver integrates seamlessly into custom cabinets, delivering professional-grade performance for discerning audio projects.
